Most package installations include compressed source files. This adds support for common archive types on Windows: * Add support for using system 7zip functionality to decompress .Z files when available (and on Windows, use 7zip for .xz archives) * Default to using built-in Python support for tar/bz2 decompression (note that Python tar documentation mentions preservation of file permissions) * Add tests for decompression support * Extract logic for handling exploding archives (i.e. compressed archives that expand to more than one base file) into an exploding_archive_catch context manager in the filesystem module
